• Major, Non-service affecting
The main processor on the TCC+ card in Slot 11 lost communication with the coprocessor on the TCC+

backplane.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454.
Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf
assembly.
